You just enter your location in the settings (click a world map or enter lat/long), and you get a "live" view of the heavens above that point and you can zoom, pan & tilt 360 degrees around you. You can speed up time to watch the planets & stars rise & set or run time backwards. Or enter a date to see what was going on in the sky at any given time.
eg. When sailing in the Gulf of St. Lawrence in Sept, I watched a spectacularly brilliant planet rise just minutes ahead of the sunrise one morning, and figured it must have been Mercury. Wrong! I used this program to go back to that date & location and "re-run" that dawn's events to learn that it was actually Venus I had seen.
Put the program on a laptop and take it outside with you at night. I did this with my nephew on the weekend. We went out with a pair of binoculars with a mission: to find one of the few spiral galaxies (M31 near Andromeda) that you can locate without a telescope. We found it! I'd read about it in books, but never actually tracked it down before. With this program, it was simple. A VR teaching aid.
Lots more features that I won't describe here. Definitely worth checking out if you have the slightest interest in the night sky.
